Sequoia sempervirens /sɨˈkɔɪ.ə sɛmpərˈvaɪərənz/[2] is the sole livin species o the genus Sequoia in the cypress faimily Cupressaceae (formerly treatit in Taxodiaceae). Common names include coast reidwid, Californie reidwid, an giant reidwid. It is an evergreen, lang-lived, monoecious tree livin 1200–1800 years or mair.[3] This species includes the tawest trees livin nou on Yird, reachin up tae 379 feet (115.5 m) in hicht (wioot the ruits) an up tae 26 feet (7.9 m) in diameter at breast hicht. Afore commercial loggin an clearin began bi the 1850s, this massive tree occurred naiturally in an estimatit 2,100,000 acres (8,500 km2) alang much o coastal Californie (excludin soothren Californie whaur rainfaw is nae sufficient) an the soothwastren corner o coastal Oregon within the Unitit States. An estimatit 95% or mair o the oreeginal auld-growth reidwid forest haes been cut doun,[4] due tae its excellent properties for uise as lumber in construction.

The name sequoia sometimes refers tae the subfaimily Sequoioideae, which includes S. sempervirens alang wi Sequoiadendron (giant sequoia) an Metasequoia (dawn reidwid). On its awn, the term reidwid usually refers tae the coast reidwid, which is covered in this airticle, an nae tae the ither twa species.
